10 years agoomap_hsmmc: Board-specific TWL4030 MMC power initializations

omap_hsmmc: Board-specific TWL4030 MMC power initializations

Boards using the TWL4030 regulator may not all use the LDOs the same way
(e.g. MMC2 power can be controlled by another LDO than VMMC2).
This delegates TWL4030 MMC power initializations to board-specific functions,
that may still call twl4030_power_mmc_init for the default behavior.

Some platforms don't have native code for dealing with their video
hardware. In some cases they use a binary blob to set it up and perform
required actions like setting the video mode. This approach is a hangover
from the old PC days where a ROM was provided and executed during startup.

Even now, these ROMs are supplied as a way to set up video. It avoids the
code for every video chip needing to be provided in the boot loader. But
it makes the video much less flexible - e.g. it is not possible to do
anything else while the video init is happening (including waiting hundreds
of milliseconds for display panels to start up).
